Back to the battery tech future

Jarret Skorup uncovers a doozie of a deja vu quote from a Detroit Free Press story published in 1967:

Companies are searching for a billion-dollar breakthrough in battery design. General Dynamics is working on a zinc-air cell battery. Ford is actively interested in a sodium-sulfur cell. Gulton Industries and General Motors are tinkering with lithium…All the activity is bound to pay off probably within the next five years.
